1. A doctrine that rejects religion and religious considerations.
2. A secular spirit or tendency; especially, a system of political or social philosophy that rejects all forms of religious faith and worship.
2. The view that public education and other matters of civil policy should be conducted without the introduction of a religious element.

The fundamental principle of secularism is that, in his whole conduct, man should be guided exclusively by considerations derived from the present life itself. Anything that is above or beyond the present life should be entirely overlooked.

Whether God exists or not, whether the soul is immortal or not, are questions which at best cannot be answered, and on which consequently no motives of action can be based.
